iStill Masher
Experience total control over the saccharification process. The automation limits labor investment and prevents variable outcomes.
Build to last
The strongest unit on the market.
The iStill Masher is manufactured from 4 to 5 mm thick stainless steel sheets, where others use 0.7 to 1.7 mm only.
That extra mass matters in the real world. It gives you a vessel that behaves like production hardware instead of lightweight process furniture.
Efficiency
The most efficient unit on the market.
Due to its compact design, insulation, and total process control, it helps save up to 30% in energy expenditure while keeping mashing behavior far more predictable from batch to batch.
Why it matters
The future of mashing. Today.
Versatility.
The iStill Masher can help make whiskey and vodka from any grain you like to work with. It can also be used for molasses clean-ups and the fermentation of beer and wine.
The future of mashing. Today.
Spirits production should not consume all of your attention. Automation reduces repetitive process work so your team can spend more time on sales, story, and growth.
Build to last a lifetime.
iStill's Mashers are made from high-quality stainless steel. It is strong, chemically inactive, and up to three times thicker than traditional mashers, boilers, and fermenters.
Complete control
Intelligent automation
The automation and robotization in the iStill Masher give you total control over the mashing production process. This helps you make the exact same top-shelf product over and over again.
Every setting, every temperature rest, every part of the run is checked every second. Computer-aided mashing removes the usual drift that comes from manual timing and inconsistent heat management.
Throughput logic
Built around the real bottleneck.
Mashing is often the production bottleneck. One well-controlled masher feeding multiple fermenters is a much cleaner setup than overbuilding the wrong part of the line.
The older iMasher workflow notes in the blog described the practical ratio clearly: mashing takes hours, fermentation takes days. That is why disciplined upstream control matters.
1 : 5masher to fermenter rhythm
One daily mash cycle can support a five-fermenter cadence when fermentation is the longer stage in the production loop.
Rethinking design
Square is the new round
Our patented flush square boiler offers unique properties. A high net filling grade of over 90% is one advantage.
Another benefit is that mixing does not create unnecessary agitation or vortex formation, resulting in better particle distribution and faster, more complete starch-to-sugar conversion.
